Wash the sticky rice and put in a pot with water. Cook till it's almost 90% done. We don't want to cook it completely.
In another pot mix the coconut milk and brown sugar, and cook for around 12- 15 minutes till it starts thickening. Take out a cup of this mixture and keep aside.
Add the cooked rice to this coconut milk mixture and cook for another 8-10 minutes or till rice completely absorbs the liquid. Switch off the gas.
Evenly spread rice on a baking dish. Pour the liquid taken out earlier and spread it evenly on top of rice.
Bake it in a pre-heated oven for around 45-50 minutes at 180 degrees Celsius.
Once done, take out the tray and allow to cool on a cooling rack. Once it reaches the room temperature, cut out pieces in desired shape and size. You can serve it warm, cold or at room temperature. Personally, I like it the most when served warm.
